Question
Chapter 22, Problem 10DYKB
Summary Introduction
Introduction:
The defense mechanisms of the body are exhibited by the immune system of the body. These immunological agents fight against foreign pathogens. Some of these responses are generalized, some are specific.

Even when the complement cascade fails to proceed beyond generating the C3 convertase, complement activation is effective at inducing pathogen uptake and destruction. This process of immune protection is mediated by: Activation of complement inhibitory receptors on phagocytes that promote pathogen uptake Activation of soluble proteases in the serum that disrupt pathogen membranes Engagement of complement receptors on phagocytes by C3b and its cleavage products which promotes phagocytosis Engagement of complement receptors on B cells that promotes antibody production Stimulation of antimicrobial peptide secretion by phagocytesarrow_forward
